Two kinds of analyses were conducted on collected data: (1) descriptive analyses conducted for each of the questionnaire items on instructional supervision; and (2) inferential analyses conducted to determine whether overall supervisory scores were associated with the demographics of gender, race, number of years working in this particular school, number of years in the field overall, and school type. This chapter of the study presents the findings observed for all performed analyses. Once findings are reported, they are discussed and interpreted in terms of the existing research reviewed in the literature.
Table 1 presents descriptive statistics (Mean, Standard Deviation, Score Range and Median) observed for each of the 51 supervisory items measured by the Instructional Supervision Survey. Regarding the general findings, it can be noted that statistics computed across survey items showed that, on the average, the level of supervisory involvement perceived by teachers was 3.47, a value midway between an involvement level of "sometimes" (a value of 3) and an involvement level of "often," (a value of 4). The median value of 3.33 was not far from the mean of the distribution of scores indicating that in the distribution as a whole, there were not mostly mid-level values accompanied by a few extreme values.
While the score range was 4.75, the overall variability of scores (scatter of scores about the mean) was not high. Indeed,
